Please forgive what may be a silly question, I am new to PostGIS.
I have the following:
SELECT ST_AsKML(
ST_RemoveRepeatedPoints(
ST_Union(wkb_geometry)
), 0
)
The beginning of the returned value looks like this:
<MultiGeometry><Polygon><outerBoundaryIs><LinearRing><coordinates>-156,20 -156,20
-156,20 -156,20 -156,20 -156,20 -156,20 -156,20 -156,20 ...
The repeated points occur several hundred times.
The docs [1] say it can be safely called with any kind of geometry.
Does anyone know what I might be doing wrong? Or of another way to
approach the problem of producing a smaller KML file (I compress to KMZ
later) with perhaps less detail?
My version info is below [2].
Thanks in anticipation
